In the Linux kernel, the following vulnerability has been resolved: bpf: Mark NULL kptr stores precise check_map_kptr_access() permits a scalar store into an untrusted kptr field only when the register is known to contain zero. Unlike other verifier checks whose outcome depends on a scalar value, it does not mark that register precise. A state checkpoint reached with an imprecise zero can therefore prune a second path that reaches the store with an arbitrary nonzero scalar. The program can write attacker-controlled bits into the kptr field and load them back as a PTR_TO_BTF_ID. Call mark_chain_precision() before accepting a known-zero register. This forces state equivalence to compare its scalar range and makes the verifier visit and reject a path carrying a nonzero value.

  - In the Linux kernel, the following vulnerability has been resolved: net/sched: act_mirred: use the backlog     for mirred ingress The test Davide added in commit ca22da2fbd69 (act_mirred: use the backlog for nested     calls to mirred ingress) hangs our testing VMs every 10 or so runs, with the familiar tcp_v4_rcv ->     tcp_v4_rcv deadlock reported by lockdep. The problem as previously described by Davide (see Link) is that     if we reverse flow of traffic with the redirect (egress -> ingress) we may reach the same socket which     generated the packet. And we may still be holding its socket lock. The common solution to such deadlocks     is to put the packet in the Rx backlog, rather than run the Rx path inline. Do that for all egress ->     ingress reversals, not just once we started to nest mirred calls. In the past there was a concern that the     backlog indirection will lead to loss of error reporting / less accurate stats. But the current workaround     does not seem to address the issue.

  - In the Linux kernel, the following vulnerability has been resolved: vfs: Don't evict inode under the inode     lru traversing context The inode reclaiming process(See function prune_icache_sb) collects all reclaimable     inodes and mark them with I_FREEING flag at first, at that time, other processes will be stuck if they try     getting these inodes (See function find_inode_fast), then the reclaiming process destroy the inodes by     function dispose_list(). Some filesystems(eg. ext4 with ea_inode feature, ubifs with xattr) may do inode     lookup in the inode evicting callback function, if the inode lookup is operated under the inode lru     traversing context, deadlock problems may happen. Case 1: In function ext4_evict_inode(), the ea inode     lookup could happen if ea_inode feature is enabled, the lookup process will be stuck under the evicting     context like this: 1. File A has inode i_reg and an ea inode i_ea 2. getfattr(A, xattr_buf) // i_ea is     added into lru // lru->i_ea 3.

However, brelse() is called by udf_rename(), too. So, b_count on buffer_head becomes     unbalanced. This patch fixes the issue by not calling brelse() by udf_rename() when udf_find_entry()     returns NULL. (CVE-2022-50755)

  - In the Linux kernel, the following vulnerability has been resolved: can: isotp: check CAN address family     in isotp_bind() Add missing check to block non-AF_CAN binds. Syzbot created some code which matched the     right sockaddr struct size but used AF_XDP (0x2C) instead of AF_CAN (0x1D) in the address family field:
    bind$xdp(r2, &(0x7f0000000540)={0x2c, 0x0, r4, 0x0, r2}, 0x10) ^^^^ This has no funtional impact but the     userspace should be notified about the wrong address family field content. (CVE-2023-54105)

  - In the Linux kernel, the following vulnerability has been resolved: usb: rndis_host: Secure rndis_query     check against int overflow Variables off and len typed as uint32 in rndis_query function are controlled by     incoming RNDIS response message thus their value may be manipulated. Setting off to a unexpectetly large     value will cause the sum with len and 8 to overflow and pass the implemented validation step. Consequently     the response pointer will be referring to a location past the expected buffer boundaries allowing     information leakage e.g. via RNDIS_OID_802_3_PERMANENT_ADDRESS OID. (CVE-2023-54110)

  - In the Linux kernel, the following vulnerability has been resolved: mtd: spi-nor: Fix shift-out-of-bounds     in spi_nor_set_erase_type spi_nor_set_erase_type() was used either to set or to mask out an erase type.
    When we used it to mask out an erase type a shift-out-of-bounds was hit: UBSAN: shift-out-of-bounds in     drivers/mtd/spi-nor/core.c:2237:24 shift exponent 4294967295 is too large for 32-bit type 'int' The     setting of the size_{shift, mask} and of the opcode are unnecessary when the erase size is zero, as     throughout the code just the erase size is considered to determine whether an erase type is supported or     not. Setting the opcode to 0xFF was wrong too as nobody guarantees that 0xFF is an unused opcode. Thus     when masking out an erase type, just set the erase size to zero. This will fix the shift-out-of-bounds.

    __x64_sys_exit_group+0x3a/0x50 do_syscall_64+0x34/0xb0 entry_SYSCALL_64_after_hwframe+0x63/0xcd The cause     of the issue is that brelse() is called on both ofibh.sbh and ofibh.ebh by udf_find_entry() when it     returns NULL. However, brelse() is called by udf_rename(), too. So, b_count on buffer_head becomes     unbalanced. This patch fixes the issue by not calling brelse() by udf_rename() when udf_find_entry()     returns NULL. (CVE-2022-50755)

  - In the Linux kernel, the following vulnerability has been resolved: soc: qcom: qmi_encdec: Restrict string     length in decode The QMI TLV value for strings in a lot of qmi element info structures account for null     terminated strings with MAX_LEN + 1. If a string is actually MAX_LEN + 1 length, this will cause an out of     bounds access when the NULL character is appended in decoding. (CVE-2023-53729)

  - In the Linux kernel, the following vulnerability has been resolved: can: isotp: check CAN address family     in isotp_bind() Add missing check to block non-AF_CAN binds. Syzbot created some code which matched the     right sockaddr struct size but used AF_XDP (0x2C) instead of AF_CAN (0x1D) in the address family field:
    bind$xdp(r2, &(0x7f0000000540)={0x2c, 0x0, r4, 0x0, r2}, 0x10) ^^^^ This has no funtional impact but the     userspace should be notified about the wrong address family field content. (CVE-2023-54105)

  - In the Linux kernel, the following vulnerability has been resolved: usb: rndis_host: Secure rndis_query     check against int overflow Variables off and len typed as uint32 in rndis_query function are controlled by     incoming RNDIS response message thus their value may be manipulated. Setting off to a unexpectetly large     value will cause the sum with len and 8 to overflow and pass the implemented validation step. Consequently     the response pointer will be referring to a location past the expected buffer boundaries allowing     information leakage e.g. via RNDIS_OID_802_3_PERMANENT_ADDRESS OID. (CVE-2023-54110)

  - In the Linux kernel, the following vulnerability has been resolved: mtd: spi-nor: Fix shift-out-of-bounds     in spi_nor_set_erase_type spi_nor_set_erase_type() was used either to set or to mask out an erase type.
    When we used it to mask out an erase type a shift-out-of-bounds was hit: UBSAN: shift-out-of-bounds in     drivers/mtd/spi-nor/core.c:2237:24 shift exponent 4294967295 is too large for 32-bit type 'int' The     setting of the size_{shift, mask} and of the opcode are unnecessary when the erase size is zero, as     throughout the code just the erase size is considered to determine whether an erase type is supported or     not. Setting the opcode to 0xFF was wrong too as nobody guarantees that 0xFF is an unused opcode. Thus     when masking out an erase type, just set the erase size to zero. This will fix the shift-out-of-bounds.

Note that Nessus has not tested for these issues but has instead relied only on the application's self-reported version number.

The Linux/Unix host has one or more packages installed that are impacted by a vulnerability without a vendor supplied patch available.

  - bpf: Mark NULL kptr stores precise check_map_kptr_access() permits a scalar store into an untrusted kptr     field only when the register is known to contain zero. Unlike other verifier checks whose outcome depends     on a scalar value, it does not mark that register precise. A state checkpoint reached with an imprecise     zero can therefore prune a second path that reaches the store with an arbitrary nonzero scalar. The     program can write attacker-controlled bits into the kptr field and load them back as a PTR_TO_BTF_ID. Call     mark_chain_precision() before accepting a known-zero register. This forces state equivalence to compare     its scalar range and makes the verifier visit and reject a path carrying a nonzero value. (CVE-2026-98034)

Note that Nessus relies on the presence of the package as reported by the vendor.
